To all who-"wit may concern:

Be it known that I, IlEnnAnN HILDE, a

citizen of the German Empire,- residing in ltosswcin, in said Empire,have invented certain new and useful Improvements in Glass-BlowingMachines, of which the following is a specification.

The present invention relates to glassblowing machines for blowinghollow glass objects, and. more particularly to machines in which theblank which is held in the preparatory mold, while the latter standsupside down on the machine table, is preliminarily pressed into shape bva comressed-air blow head, after which the preiminary mold is swung overto the blow head by which the blank isroughly blown while said mold isin upright position. The I rises, the mold beneath the sarne'lsautoblank is then taken out of mold and transferred to the finishingblowing device. In the machines of this character at present in usethere is usually but one mold, which is fixed to a shat t journal-ledon'the machinetable between the com ressed-air blow heads of thepressing and )lowing devices, By

this shalt the mold is swung to and fro between the two devices. With aview to relieving the attendant, the swinging axis is so coupled to thefirst blow head that on the rising of the latter the mold isautomatically swung beneath the second or blowing blow head, and afterthe blowing and discharging have been effected the mold is swung backagain by the rising of such second blow head. The movement of the blowheads in this tpe of machine is mechnnirnlly produced y compressed-aircylimlers controlled by the workmen.

The present invention aims. to increase the capacity of the machine bvproviding two molds which are movable about a com- A further objectofthe invention is to provide a machine in which the molds during theoperations of pressing and blowing stand on the machine-table and underthe res ec- Accordingly a. specia arrangement of the molds on theswinging axis becomes necessary, so that they can be swung in a circlewitiout abutting against mold-is swinging around at the top, the

oinpty one comes around at the bottom, to be. broughtalternate-l .-uthat it idnecessary that the molds be displaceable .nlong their axis inorder that the the tableof the machine and after swinging back be movedback under the pressing blow head. In the present invention, for afurther'relief of the attendant, the move ment of the molds is effectedautomatically bv connections with the com 'ressed-air blow heads, whichare mechanical y operated.

With these ends in view, the new mach neis so devised thaton the;;firstcompressedair blow head moving hack after the pressing operation, thepreparatory mold,- which has been standing upside down beneath said blowhead, is turned through 180 and transferred over to the blowing device;at the same time the preparatory mold of the blowing device swings backto the pressing or head-forming device. When the second blow head,belonging to the blowin" device,

In this manner the o'ierator is quite mate-' riallv relieved, as he msno other duti but to close the mold contained within the head: formingor pressing device and to keep the machine running in the usual way bycontrolling the blow heads.

In the accompanying drawings, in which the same reference charactersdenote the same parts throu hout the figures, Figure 1 is an elevation oa lass-blowing machine constructed in accor ance withthe invention, theblow headsbeingraised and one of the molds being open and the otherclosed, Figs. :2 and 3 are detail horizontal sections of. Fig. 1, Fig. 4shows in detail the head:

forming device with its hcad form open and the pressing blow hen-dmoving upward,

blowing device with its blow ,head moving-i upward, and Figs. 9 and 10show in plan" the device for 'unboltmg and-opening the molds.

In the drawingsb b denote'the preparatory- I molds which are to beinterchanged, i.

relation with the. head-saping'or pressing device a and the blowingdevice a. :These' empty one may mo o 'l laterally beyond i'niolds aremounted on the table of the into cooperative 10- that said box isrotated in the bearing 11-.

the wheel 8 prevents the machine and the pressing device and blowingdevice are arranged side by side above said table, as shown in Fig. l.The molds b b are attached to arms (1 d which extend laterally from.sliding bars 1 g which are movable in forward and backward di rection,and parallel with each other, over the machine-table, as shown in Fig.'2. Said sliding bars are movable longitudinally in a box It which ismounted to rotate about its axis in a hearing it. The box h carries arearwardly directed extension at the end of which a rolleri is mountedover which a rope k, connecting the sliding hats g g, is passed in orderto produce th movement of said bars in opposite directions. Both slidingbars 5 g carry at their ends, which are directed toward the table, hooksm behind which at a given moment a catch it carried by a rack-slide oengages itself in order to con le one or the other of said bars with lsai slide. Said slide is movable in forward i and backward direction ina guide in the machine-table and has formed on its under surface a rackwhich engages a toothed wheel or pinion q mounted on a shaft 11 underthe table. Said shaft can he put in motion by means of a system ofgen-ring to he presently described.

The pressing device a is provided with a blow hen-d t guided vertically.The guiderod 8 of said blow head has applied thereto a plate 11' Eizichslides vertically in a slot 12'' of a raek-slide e which is movable infixed guides. By means of links 10 a vertically moving rack .r' islinked to this slide, and said rack engages with n. toothed wheel 2fixed an a shaft 3 as shown in Figs. l and 3. The rack .r is soarranged, by means of the links '11), that, yielding upwardly on thedescent of the slide o, it is disengaged from the toothed wheel z andthus becomes free to move downwardly without setting the she-ft y inmotion. A pawl z concting with shaft 3/ from turning in the wrongdirection. At the other end of the shaft y a rope-pulley r is fixed fromwhich, by means of a rope r" and a second ulle r, rotary motion istransmitted to the ox. in which the bars a g are guided, so

The blowing device a is. provided with a blow head t similar to the blowhead t. The guide-rod 2 of this b ow head i carries a laterallyextending plate 3 which engages a slot 4 )IOVlt'lQtl 1n a verticallymoving rack 5. aid rack is mcvnble in suitable fixed guides and engagesa toothed wheel or pinion 7 moving loosely on a pivot 6, as shown inFig. 3. Said wheel transmits Z rotary motion to another and similarwheel 8 mounted on a shaft 9 at the opposite end i "of which-there is arope pulley 10. By I means of-the pulley l0 and a ropellrotar'y I motionis transmitted to a double pulley 13 i fixed to a shaft 12. A rope 14connects said double pulley with'a pulley 1.5 having a shaft 16,whieh'is, by the rope-drive 17, connected with the shaft 18. By theropedrive 19 said last-named shaft is connected with the shaft 11.Accordingly the downshaft 24. On the shaft 24, at the end opposite thewheel 25, is a rope-pullev 26 from which rotary mot-ion is imparted bymeans of'a rope 27 to a rope-pulley 28 mounted upon a shaft 29. Saitlpulley 28 is connected by a rope-drive 30 to t 1e horizontal shaft 31which rotates, by means of a )air of bevel ears, an upright shaft ll tenthe blow lead t is rising an entire turn is imparted by the gearing justdescribed to said shaft 33 at theup er end of which a thumb-disk 3-1 issecured? The thumb on said 'disk is provided for the v urpose ofreleasing the lid of the mold, and t- 18!! in the further course of itsmotion to open such mold. The molds b b, which as usual are dividedlengthwise, are held by frame-parts 35 and 36 which are adjustablymovable on the arms d d. By means of two armed levers 37 movable aboutbolts 38 on the arms d 11 both frameparts 35, 36 are in reciprocalconnection, so that on displacing part 36 the other part 35 is displacedin the opposite dircctitm.

Between corresponding heads of the frame-parts 35, 36 on the arms (I d amovable plug 40 of elongated shape is movable about a bolt 39. ()nclosing the mold said plug is to he moved bv hand into the positionshown in Fig. 2 at the left. On one leg of this plug 40 a draw rod 41operates, the extremity of which is provided with a slot 4; which passesover the pivot 43 of a latch 44 on the frame-part 36. The length of thed raw-rod 4.1 and the slot 42 is so dimensioned that, on the plugoccupving the closing position, the hitch 44 will be moved away from itsbuck-ledge 45 by the draw-rod 41, so that when the thumb 34 shotsagainst the latch 44 the latter is moved back to the butt end of theback-ledge 45 of the frmnc-pnrt 36. In this way the plug 40 is givensuch an oblique position that, being moved back by the thumb 34, it canbe adjusted in an oblique position to arm (I or d.

The operation of the improved machine is as follows: npposing the mold bto be. closed 5 and placed vertically under the blow head i of thepressing or heml shnping device a and the blank previously blown to havebeen freed in the blowing device 0- by opening the mold b, then on thedescent of blow head t is attached a plate 21 to whichv is still behindthe'blow head t.

the rack x will pass by the toothed wheel 2 without settin the shaftyinmotion. When,

after sha ing t e head of the blank and after 1 the usua opening of thedivided head-mold held last on the machine-table, the blow head I ismoved upwardly again, this causes theplatc u to'oarry along the slide'1: with the rack I. Said rack through the toothed wheel z and shaft yoperates the driving gear r 1" 'r in such a manner that the box 2! willbe turned through 180%) that the mold b, which before stood upside downon the table, is now moved upright under the blowing device a. At thesame time the mold b is swung over in. opposite direction and is kes theilace of mold bgvith its head downward, with t e diiierence, however,that said mold I), ha vin been previously moved ba cl-rwardly beyondthe. table, After the head-part of the. blank rotruding from the mold bhas been inclose by the headqnoldf associated in the usual way with theblowing device, the blow head i is "moved down on the mold b and theblank roughly blown. On this downward movement of blow boa-d t the rack5 is moved downwardly and through the medium of the wheels 7, S, theshaft 18, the rope-drive 19 and the toothed wheel q,

' the rack-slide 0 is moved backward sot-hat its catch 11- engagesbehind the hook 11" of the sliding bar 9. In this why said sliding baris coupled with the slide 0. When the blow head i is raised a ain. thenat the very outsetof its UPWBH movement the rack 23,

, through the connections described, rotates the upright shaft 33 andthumb-disk 34 so that the latter unbolts themold-frame 35, 36

in the manner above described in order to set the blank free. On openingthe mold bthe platei will have reached the end of the slot 4, andaccordingly the rack 5 will be forced to follow the upward movement ofthe blow head. Hence said rack through th connections described willpush'forwn-rd thie rackslidc 0 whereby the sliding bar will be movedforward and the sliding bar g moved backward. The latter sliding barcarries along with it the mold I, which will b moved baa-lm'ard beyondthe edge of the table. When the blow head t of the head-shaping deviceis moved upwardly again, said mold b will be swung back within reach ofthe headshaping device, as before described. At the some time the mold bis moycd backward the. mold l)" is moved forward into position on themmzhine-t-able under the blow head t. The halves are then closed byhand, whereupon the above described operation can recommence.

llaving thus described my invention, I claim as new and desire to secureby Letters Patrnt: V
